SPECIFICATION forming part of Letters Patent No. 526,004, datedSeptember 11, 1894.

Application filed May 7,1894. Serial No. 510,429- (ModeL) To all whom itmay concern.-

Be it known that I, MATT BAOKSTROM, a citizen of the United States,residing at Austin, in the county of Potter and State of Pennsylvania,have invented a new and useful Shipping-Crate Cover and Devices forFastening the Same, of which the following is a specification.

My invention relates to improvements in the adjustment and fastening ofthe covers of egg and berry crates used in the shipment of suchmerchandise; andthe object of my device and improvement is to provide aneat and convenient crate cover, easily and quickly adjusted and solidlyfastened, and which may be locked, unlocked, laid aside and preservedfor further use without nailing, marring or breaking. I attain theseobjects by the devices illustrated in the accompanying drawings, inwhich- Figure 1 represents an open box or crate of any required size ordepth, with broadheaded nails or screws inserted perpendicularly in theend boards of the box, or crate, A, B, B, c, d,d,-A and B to be highenough to admit cover, with lock bars under the head, and B, c, d, 01,just high enough to admit and hold cover firmly.

Fig. 2 is the cover mortised at A, B, B 0, d, d, to correspond to nailsin crate, A B, B*' deep enough to admit cover to slide sufficiently tolet cover at mortises 0, cl, d go under nail heads 0, d, d, in Fig. 1. Ois a cleat screwed on the cover, slightly diagonal, and near the end 0,d, d, beveled or rabbeted on inner edge under side. g, h, are wiresprings, working like springs of umbrella handles.

Figs. 3 and 4 are look bars; the ends A B to be inserted by mortiseunder nail heads A, B in Fig. 1 after the cover, Fig. 2, is in place. Bya side movement of lockbars sidewise at below the springs g, h, on cleatthe beveled or tenoned ends of bars, g, h, slip above the springs whichhold the bars in place, and the pressure upon the diagonal cleat holdsthe crate cover solidly in place.

I am aware that crate covers in abox form, with locks of Variousdevices, upon the ends or sides, have long been in use; but

What I claim as my invention is- The device for adjusting a flat coverto crates by means of mortises in ends of cover as shown in Fig. 2, andbrads in Fig. 1, A c, &c., and the firm lockingin place of cover bymeans of lock-bars Figs. 3 and 4 in connection with beveled cleat, O andsprings g, h.
